It's far too easy to say "Oh, I know I would never do that."
I'm no expert, but I would imagine that the majority of suicide cases are severely depressed - you'd have to be, by definition.
And by "depressed", I mean complete with clinical diagnosis, not just a bit fed up.
Clinical depression causes changes to the brain's chemistry and you literally become a different person to the one all your family and friends know, therefore, things which you would never have imagined possible and actions well out of previous character become eminently feasible.
It's a complicated subject and you can't just throw a blanket over everybody who feels so bereft of hope that they take their own life and label them cowards.
As for Brazil, I don't think he should be sacked....just told to stop and think more in future before offering his "considered" opinion.
